Abstract
The present invention discloses a method for preparing boiler fuels by metal bath to crack waste tyre rubber and plastic. The present invention is characterized in that slices of tyre rubber, or waste plastic is directly contacted with heat carriers (zinc, stannum, antimony, bismuth, aluminium and lead which are in molten states) for the metal bath in a cracking kettle; because the steam is a good catalyst, the cracking reaction is accelerated under ordinary pressure and at a temperature of 250 to 450 DEG C; boiler fuels and carbon black can be recovered by cooling a recovery device; the heat carriers for the metal bath can be repeatedly used, and the loss is little. The present invention has the advantages of no need of complicated catalyst crackers, high petroleum product recovery rate, high speed, safety, low cost, and energy and working hour saving; simultaneously, the equipment turnover rate is accelerated; the present invention solves the defects of the prior art for preparing oil by waste tyre rubber and plastic, and effectively treats white pollution.
Description
Technical field:
The present invention relates to method with metal bath cracking scrap tire rubber, plastics-production boiler oil.
Background technology:
At present various motor vehicle is gone up by society, bike, and travelling belt, the sebific duct usage quantity constantly increases, because constantly running, changes and scraps rubber for tire and grow with each passing day, and also has various depleted plastic packaging bag.Formed environmental pollution,, will seriously threaten the space of human survival, destroyed the eubiosis if can not finely utilize.According to described scrap tire rubber, the plastics-production gasoline, diesel method utilized of patent of invention ZL03134661.8, only delivering of patent documentation just has 100 parts more than, and consistently generally acknowledges that adopting scrap tire rubber, plastics-production gasoline, diesel oil technology is a kind of method that reclaims waste rubber, plastics preferably.See with regard to present disclosed patent documentation, existing method with scrap tire rubber, the living gasoline, diesel of plastics mainly is to scrap tire rubber, plastics complicated catalytic cracking technology and complex apparatus, heat with straight burning of fire then, cracking gasification back condensation obtains processed oil.There is following deficiency in aforesaid method:
1, needs complicated catalyst cracker and expensive catalyzer.
2, with naked light direct heating waste rubber or the plastics inequality of in melting process, being heated.Low when high during temperature, become charcoal if just be easy to coking after temperature surpasses 400 ℃.When the still bottom coke has just formed a thermofin behind 2～3 centimeters of thickness, just be difficult to the fusing of cracking more later on, even can't continue operation again.
3, waste rubber or plastic cracking are thermo-negative reaction and gasifying, and the heat conductivility of its material is relatively poor.In the long-time cracking of high temperature, at the bottom of the still and the inevitable coking charing of still wall, reduced the Oil Recovery rate.
4, cracking still is generally used the carbon steel manufacturing, directly burns with naked light for a long time, and its welded seam is easy to seepage because in the still pyrochemistry gaseous corrosion is arranged.Because directly burn, be easy to deform and scrap with naked light.
5, after cracking finishes, during the cleaning waste residue, there are a large amount of dust from flying to pollute surrounding environment.
6, the terminal waste gas of prolong fails to reclaim, thereby certain stink contaminate environment is arranged.
Summary of the invention:
Technology of the present invention is dealt with problems and is: provide a kind of equipment simple, inexpensive, durable, the efficient height fast and safely, does not need complicated catalyst cracker.The metal bath thermophore is reusable, and loss seldom.Oil product transformation efficiency and rate of recovery height, quality better, the low save energy of cost and industrialization cracking scrap tire rubber, the plastics-production boiler oil in man-hour.Thereby the defective that the method that efficiently solves existing scrap tire rubber, plastics-production gasoline, diesel exists.
Technical scheme of the present invention realizes in the following way.Damaged tire is cut into 100 * 100mm fragment with slicing machine.Add earlier 30 kilograms in 70 kilograms on zinc and tin in the cracking still of iron casting, then will crumb or plastics be heating pyrolyze after adding the prolong that is tightly connected in the cracking still.350 ℃～400 ℃ of cracking temperatures.Gas after the cracking is boiler oil after cooling.After cracking finishes, black in settling tank with water-jet pump vacuum drawn still blowing-in burden(ing).The prolong end receives oil groove mouth upper end and adorns a vacuum fan, can not cause the beneath burning of cooking stove by refrigerative trace waste gas, has so just thoroughly solved dust and waste odour-gas environmental pollution.
Boiler oil processing method and equipment that the present invention produces are simple, operation easily, and fast and safely, cost is lower.Can extract boiler oil more than 55%, carbon black 25% with scrap tire rubber calculating.Utilize waste tire rubber or industrial waste plastics-production boiler oil, can receive utilization of waste material, resource recovery reduces the pollution to environment, benefits the nation and the people.Present method does not have waste gas, waste water, waste sludge discharge.Thoroughly solved the technical barrier of white pollution.
Embodiment:
Following embodiment is further described in detail the present invention: but 300 kilograms of 700 kilograms of fusion plastic waste of present embodiment scrap tire rubber fragment, and real altogether is 1 ton.Earlier 30 kilograms in 70 kilograms on zinc and tin is added in the cracking still (preferably plumbous, but its steam is poisonous) as the bedding course heat-transfer medium, i.e. the metal bath thermophore.Drop into 700 kilograms of scrap tire rubber fragments and 300 kilograms of adulterants of plastic waste then and be 1 ton altogether, sealing post-heating to 350 ℃～400 ℃.This moment, metallic zinc and tin began earlier to dissolve, and formed a metal bath thermophore, i.e. the metal bath thermophore bedding course of molten state, can A.T.C about 350 ℃, this is the best cracking temperature of scrap tire rubber and plastics.Its steam is the good catalyzer of waste rubber.In 10 minutes, begin cracking, produce gas, after the condenser cooling, become liquid, cause Receiving bin and be the finished product boiler oil.
In cracking and process of cooling, there is a spot of waste gas to fail to be condensed to liquid at the reception notch.This waste gas that can not cool off recovery is guided to the burning of cracking still cooking stove with vacuum fan, thoroughly solved the waste odour-gas environmental pollution.After cracking finishes, carbon black in the cracking still vacuumized with the water-jet pump cause pond precipitation, thoroughly eliminated the dust environmental pollution.
1 ton of scrap tire rubber fusion of cracking plastics, 600 kilograms of liquid boiler oils of separable recovery, 250 kilograms of carbon blacks.
